To a whom it may concern:

Be it known that I, CLARENCE A. Knve, of]

State of New York, have invented new anduseful Im rovements in Acetylene-Gas Gen i which the following, taken in connection a full, clear, and exact description.

This invention relates to rovements in acetylene-gas generators, an refers more for feeding the carid in limited quantities from the superposed hopper to an underlying Water-chamber. In

.devlces of this character the feed of the carbid is usually controlled automatically by the amount of gas generated, and it becomes of.

the utmost importance to render this automatic feed as positive in action as may be practical, so that only such quantities of the carbid are fed'from the storage-hopper into the water-tank as may be required to maintain a predetermined quantity of gas in the gas-holder, and in doing this it becomes necessary to provide some means for relieving the weight or pressure of the carbid upon the valve which regulates the feed of such carbid per or storage-reservoir for the carbid withthrough the outlet of the hopper and also to construct the valve in such manner that the resistance'to its opening will be reduced to a while at the same time it must quickly cut off further feed of the carbid when allowed to close.

My object, therefore, is to provide a hopa, funnel-shape discharge-nozzle in which is seated a hollow conical valve having a sharp or knife-shape lower edge or base adapted to seat against the inner face of the discharge.

nozzle to close said opening, the apex of said valve being uppermost, so as to readily'pass through the overlying carbid when the valveis opened."

Another object is to loosely mount, this valve upon an oscillator stem, so that it may readily adjust itsel to its seat when closing and also to better enable it to work upwardly through the carbid when opening.

A further object-isto provide a hood or bafHe-plate a sufiicient distance above the valve to allow the latter to open a limited distance and at. the same time'to support a greater body of the carbid free from the valve, such hood or bafiie-plate being of slightly less diameter than the inner diameter of the adjacent portion of the carbid in which it is located to allow the :carbid tofeed exhaustion of the around its margin to thennderlying generator.

A still further'object is to encircle the dis? charge end of the ho per with a suitable water-ring capable of 'scharging jets of water against the sides of the feeding-tube w connects the hopper to the water-tank.

Another object is to mount the valve-opcrating shaft in the connecting-tube above the water-line and to provide said shaft with a crank-arm projecting into the path of an operating member upon the bell of a as-receiver, so that when the bell is lowerediy the as therefrom it operates the crank-arm an rock-shaft to open the valve and allow additional carbid to enter hich the water-chamber for the production of more gas.

Other objects and uses will be brought out in the following description.

' In the drawings, Figure 1 is a vertical section, partly in elevation, of a portion of a gasgenerator, showing particularly my improved carbid-feeding device and its 0 crating mechanism, including a portion 0 the gas-reservoir. Fig. 2 is a sectional view taken on line 2 2, Fig. 1. Fig. 3 is an enlarged sectional view of the lower end of the carbid-reservoir and valve therein.

In demonstrating the practicability ofmy ,invention I have shown a portion of a watertank 1 as provided with an upwardlyrojecting tube 2, to the upper end of Whic is attached a hopper or storage-reservoir 3 for the carbid, said reservoir having an inletopening in its upper end normally closed by a cap 4 and clamping device 5 to prevent the escape of gas. The lower end of this reservoir is funnel shape and is provided with a suitable outlet-opening 6, discharging into the upper end of the tube 2, which forms a conduit to delivery the carbid into the upper end of the generator 1.

A hollow cone-shape valve 7, having a lower knife-edge 8, is adapted to seat against the inner face of the lower end of the hopper 3 just above the outlet 6, while its apex is up permost and is loosely mounted upon the upper end of an oscillatory rod or stem 9 be-,

tween two shoulders, as nuts 9, whereby the valve and its stem are locked against relative endwise movement. The object of loosely mounting the valve upon an oscillatory stem is to enable the valve to. readily adjust itself to its seat. in the lower end'of the hopper, and thereby prevent excessive feed forms a more perfect seat with the outlet endof the hopper.

The hood 10 is mounted upon a suitable cross-bar or equivalent support 11 directly over and a sufiicient distance above the valve 7 to bear the weight ofthe greater portion of the superpose body of carbid, and thereby prevent excessive oad or pressure upon the valve 7, which t tend to resist its opening, said hood or b it e-plate being of slightly less diameter than the interior diameter of the adjacent portion of the hopper in which it is located to allow limited quantities of the carbid to pass downwardly around the sides of the hood and against the sides of the valve; It is now obvious that the carbid which feeds downwardl around the shield or hood 10 lies against t e downardly-converging sides of the ad'acent portions of the ho per and valve, an the uanp withdrawing the pressure of the shoulder 15 from the ad -acent end of the lever 14 and al tity of carbid ying against the valve eing comparatively small it is evident that but, little resistance is offered-to the opening ofthe valve, particularly when itisconsidered that the upperend of the valve is taperin and readily wedges throu h the li ht body 0 the carbid below the shie d 10. he valve 7 is therefore opened with but -a compara tively light ower or upward pressure, which is effected t ough the medium of a rock-arm 12 and rock-shaft 13, ha one end extended through one side of the shell 2 and provided with a lever 14, which projects into the path of an operating-shoulder 15, carried by t e bell, as A, of the gas-receiver.

The lower end of the stem 9 is pivoted at 16 to the inner end of the rock-arm 12, which is secured to the shaft 13rwithin the shell 2. This rock-shaft 13 is mounted in the shell 2 above the waterline of the generator 1, and

its outer end extends through a suitable prevent the escape of gas stuffing-box 17 to therethrough.

The lever 14 is centrally-secured to the outer end of the rock-shaft 13 at the outer side of the shell 2 and has one arm extending in the direction of extension of the rock-arm 12 and is provided with a suitable counterweight 18, which is sufiiciently heavy to close the valve 7 through the medium of the rockshaft 13, rock-arm 12, and connecting-rod 9. The other arm of-the lever 14 is provided with a shoulder 20, which is disposed in the 6o path of the operating-shoulder 15. This shoulder 15 is adjustably secured to a vertical rod 21, which is guided at its lower end in suitable bearings 22 on the side of the outer shell, as a of the reservoir, while the upper end of said rod is attached, by means of suitable braces 23, to the bell A of the gas-reservoir, so that as the bell descends by the exhaustion of the gas therefrom the rod 21 will be similarly depressed and bring the shoulder 15 into operative engagement with and depress the adjacent end of the lever 14 against the action of the counterweight 18, thereby o ening the valve 7, allowing the carbid to dlscharge through the opening 6 and tube 2 into the generator li or producing additional gas, such glass being conveyed from the gener- 'ator 1 to te gas-reservoir inanywell-kncwn manner, not necessary to herein illustrate or describe, as the manner of connecting the generator to the reservoirforms no part of my present invention. It is now cie'ar that when the valve 7 is opened in the manner just described to ailow the entrance of earbid from the reservoir 3 to the generator the lowing the latter to b'e'returned to its normal position by the-weight 18 to close the valve 7, and should an 'ohunks-of-carbid t under the knife edge o 'thevalve it wo be more or less liable to be cut-int'Wo', or else the valve will use sidewise toadjust itself to its seat to prevent the further reed ofthe carbid through the opening 6. During this feedof the carbid through the tube 2 more or less willaccumulate upon the sides of the tube,-

and in order to remove this I provide a wee ter-ring 25 around the-lower end or the hopper and within' the upper end of the tube, said water-rin being provided withradial openings 26, ischarging against the inner sides of the tube 2 and serving to clean it from any adhering material and to deposit it into the underl enerator, the waterso lybein controlle bya suitablevalve27;
